According to remote server’s commands, the malware can steal user’s SMS messages and MMS messagesand upload them to remote server via secure FTP. It will also upload the complete file list from the user’s SD card to the remote server. Then remote server will control the malware to upload specific files. This is a severe threat to user’s privacy and sensitive data.

TrustGo Security Labs successfully accessed the FTP server and discovered uploaded files from some victims. The following is the root directory of the FTP server.
